Curtis: How can the G20 help save the euro zone?
This is largely an intra-European problem, and thus will have to be sorted out primarily by the Franco-German “alliance” with help from the other, smaller EU members.
The G20 have, and should, focus on the systemic implications of the current problems, through moral suasion and lending where it’s possible (viz. China) and in national/systemic interests of each G20 member. As a group, the G20 should suggest further co-ordination of policy to lay the basis for sustainable growth.
